A.
The zoning districts established by this chapter are designed to guide future use of land in the Borough by encouraging the development of desirable residential, commercial and manufacturing areas, with appropriate groupings of compatible and related uses to the end of promoting and protecting the public health, safety, comfort, prosperity and other aspects of the general welfare. To achieve this end, lawful existing uses which would be prohibited or restricted under the terms of this chapter or future amendments, which do not conform to the character and regulations of the zoning district in which they are located must be subject to certain limitations. The regulations set forth below are intended to provide a gradual remedy for the undesirable conditions resulting from indiscriminate mixing of uses and to afford a means whereby nonconforming uses can gradually be eliminated and reestablished in more suitable locations within the Borough. Similarly, buildings or other structures which do not comply with one or more of the applicable district area and bulk requirements as further listed in § 360-36 are deemed to be nonconforming. Nonconforming uses and structures will be generally permitted to remain; the purpose of regulating them is to restrict further investment in uses or structures which are inappropriate to their location.
B.
To avoid undue hardship, nothing in this chapter shall be deemed to require a change in plans, construction or intended use of any building on which actual construction was lawfully begun prior to the effective date, or amendment, of this chapter and on which actual building construction has been diligently carried on.
